24 FOSSIL FISHES OF LOMPOC 



9. Zaphleges longurio Jordan, new species. 

 (Plate XIII) 



Type No. 100, a very fine example, 18> l /2 inches long, showing the 

 entire fish, the head crushed, the first dorsal, ventrals, anal, and ribs 

 injured. 



Head 3y 2 in length to base of caudal ; depth 6^ ; head moderate, 

 rather pointed; half of lower jaw preserved; this with about 60 slender, 

 pointed teeth apparently in one row, rather small anteriorly; no trace 

 of canines; part of gill arches with fringes preserved; bones of head 

 apparently all entire. 



First dorsal inserted not far behind head, somewhat displaced in 

 the type ; 8 or 9 slender, low, close-set spines preserved ; one or two longer 

 detached spines preserved behind it, these probably not belonging to 

 this fish. Soft dorsal of about 25 slender rays, the anterior longest ; anal 

 fin detached, partly obliterated, the interhsemals all lost ; first two rays 

 apparently short, slender spines ; about 12 rays preserved, its insertion 

 behind front of soft dorsal ; caudal fin very long and strong, well forked, 

 its lobes equal, exceeding depth of body, outer rays much shorter, like 

 fulcra, the number 9, 10 10, 9, the peduncle not very slender, with 

 strong neural and haemal spines on each vertebra. Pectoral fin inserted 

 opposite curve of opercle, rather broad and shortish, of 16 to 18 rays, the 

 fin not symmetrical, the lower rays rapidly shortened. Ventrals inserted 

 just below pectorals, largely obliterated. 



Vertebrae about 54, slender, constricted, longer than deep ; the neural 

 and haemal spines rather strong ; ribs lost : interneurals of soft dorsal 

 long, rather strong, and very oblique. 



Scales preserved in various parts of the body, rather small, cycloid 

 (apparently about 60 in a row). 



Note on ZELOSIS Jordan and Gilbert, new genus : Type CLUPEA HAD- 

 LEYI Jordan and Gilbert (Fossil Fishes of Southern California, p. 29). 

 The fish described by us a CLUPEA HADLEYI is certainly not a true herring, 

 and it bears a striking resemblance to ZAPHLEGES LONGURIO in its general 

 form, squamation, vertebral column, and rudimentary caudal rays. But its 

 ventral fins are plainly abdominal (not clearly shown in the plate), there 

 is no trace of spinous dorsal, the caudal fin is much smaller with much 

 shorter caudal peduncle. The dorsal and anal fins are far back and op- 

 posite each other as shown by the interspinals. It may be made type of 

 a genus ZELOSIS (ZeXooi?, imitation).
